A dual shock absorption landing leg assembly for a drone

Abstract

A dual-shock-absorbing outrigger assembly for unmanned aerial vehicles (UAVs) belongs to the field of UAV technology. By setting up a shock-absorbing assembly, and utilizing the first and second shock-absorbing rods in the assembly, dual shock absorption can be achieved. When the UAV lands, the first shock-absorbing rod supports the fuselage and prevents the impact from being transmitted to the fuselage and causing damage when the outriggers impact the ground. The second shock-absorbing rod can pull and tug on the outriggers, and provide a certain degree of flexibility when impacted, thus buffering the impact when the outriggers contact the ground and effectively reducing damage to the fuselage.

Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a dual shock-absorbing outrigger assembly for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently.

[0003] When a drone lands, its own weight and inertia will generate an impact force, and the frame will contact the ground. Drone shock absorption devices are usually used, but existing drone shock absorption devices can only absorb shock through a single structure, which is poor and ineffective. This causes internal parts of the drone to vibrate during landing, resulting in damage to the parts and making it unsuitable for human use. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a dual shock-absorbing outrigger assembly for unmanned aerial vehicles.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a dual shock-absorbing leg assembly for unmanned aerial vehicles, including a mounting rod base, a set of shock-absorbing components are connected to the four corners of the mounting rod base, and a leg is connected between the ends of the shock-absorbing components on the left and right sides.

[0006] The mounting rod base has a mounting rod on both the front and rear sides. Each of the mounting rods has a hinge hole and a sliding groove symmetrically located at both ends. The hinge hole is located at the end of the mounting rod, and the sliding groove is located inside the hinge hole.

[0007] The shock absorption assembly includes a first shock absorption rod, a tie rod, and a second shock absorption rod. Both the first and second shock absorption rods include a fixed end and a movable end. The fixed end of the first shock absorption rod is provided with a first hinge seat, and the tie rod is provided with a second hinge seat.

[0008] The support leg is symmetrically provided with two third hinge seats, and a fourth hinge seat is provided on the inner side of the two third hinge seats.

[0009] The upper end of the first shock absorber is hinged to the hinge hole of the mounting rod, and the lower end of the first shock absorber is hinged to the third hinge seat of the support leg. One end of the pull rod is slidably connected to the sliding groove of the mounting rod, and the other end of the pull rod is hinged to the first hinge seat of the first shock absorber. The second shock absorber is hinged between the second hinge seat and the fourth hinge seat.

[0010] Preferably, a set of drive components are symmetrically arranged in the mounting rod seat, and the drive components include a drive cylinder and a push rod.

[0011] Preferably, the front and rear ends of the push rod in the drive assembly on the left and right sides are connected to the upper ends of the pull rod in the shock absorption assembly on the left and right sides.

[0012] Preferably, the drive cylinder is hinged between the mounting rod seat and the push rod.

[0013] The beneficial effects of this utility model are as follows: By setting up a shock-absorbing component, and utilizing the first and second shock-absorbing rods in the shock-absorbing component, dual shock absorption can be achieved. When the drone lands, the first shock-absorbing rod supports the body and prevents the impact from being transmitted to the body and causing damage when the outriggers impact the ground; the second shock-absorbing rod can pull and tug on the outriggers, giving the outriggers a certain degree of flexibility when impacted, and acting as a buffer when contacting the ground, which can effectively reduce damage to the body.

Detailed Implementation

[0018] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0019] Example: A dual shock-absorbing leg assembly for a drone, such as Figures 1-3 As shown, it includes a mounting rod base 1, and a set of shock-absorbing components 2 are connected to each of the four corners of the mounting rod base 1. A support leg 3 is connected between the ends of the shock-absorbing components 2 on the left and right sides.

[0020] The mounting rod 4 is provided on both the front and rear sides of the mounting rod base 1. Each of the left and right ends of the mounting rod 4 is provided with a hinge hole 5 and a sliding groove 6. The hinge hole 5 is located at the end of the mounting rod 4, and the sliding groove 6 is located inside the hinge hole 5.

[0021] The shock absorption assembly 2 includes a first shock absorption rod 7, a tie rod 8 and a second shock absorption rod 9. Both the first shock absorption rod 7 and the second shock absorption rod 9 include a fixed end 10 and a movable end 11. The fixed end 10 of the first shock absorption rod 7 is provided with a first hinge seat 12, and the tie rod 8 is provided with a second hinge seat 13.

[0022] The support leg 3 is provided with two third hinge seats 14 symmetrically arranged front and back, and a fourth hinge seat 15 is provided on the inner side of the two third hinge seats 14.

[0023] The upper end of the first shock absorber 7 is hinged to the hinge hole 5 of the mounting rod 4, and the lower end of the first shock absorber 7 is hinged to the third hinge seat 14 of the support leg 3. One end of the pull rod 8 is slidably connected to the sliding groove 6 of the mounting rod 4, and the other end of the pull rod 8 is hinged to the first hinge seat 12 of the first shock absorber 7. The second shock absorber 9 is hinged between the second hinge seat 13 and the fourth hinge seat 15.

[0024] A set of drive components is symmetrically arranged in the mounting rod seat 1. The drive components include a drive electric cylinder 16 and a push rod 17.

[0025] The front and rear ends of the push rod 17 in the drive assembly on the left and right sides are connected to the upper end of the pull rod 8 in the shock absorption assembly 2 on the left and right sides.

[0026] The drive cylinder 16 is hinged between the mounting rod seat 1 and the push rod 17.

[0027] The principle of this utility model is as follows: In use, the outrigger assembly is installed to the bottom of the drone body through the mounting rod 1. After the drone takes off, the drive cylinder 16 in the drive assembly pulls the push rod 17 outward, causing the upper end of the pull rod 8 to move outward. At this time, the first shock absorber 7 flips upward under the drive of the pull rod 8, thereby causing the outrigger 3 to tilt upward, which can prevent the outrigger 3 from hitting obstacles during flight. When landing is required, the drive cylinder 16 drives the push rod 17 to move inward, causing the upper end of the pull rod 8 to slide inward, thereby pulling the first shock absorber 7 down to support the drone.

[0028] The two support legs 3 on the left and right sides are supported by two sets of shock-absorbing components 2 on the left and right sides. The second shock-absorbing rod 9 pulls the support legs 3 from the side, playing a flexible supporting role. The first shock-absorbing rod 7 provides the main support for the support legs 3. When subjected to impact, both the first shock-absorbing rod 7 and the second shock-absorbing rod 9 will retract to achieve a buffering effect.

[0029] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
